This ‘female’ identity Graham is attributing to an entity apart from his psyche is close tot eh anima characters Jung defined as part of the collective unconscious. Without any drugs, while going through Jungian analysis I met some of these female identities, like the four-eyed anima. Graham is just into mysticism where he can connect it to rebellious use of mind altering drugs. I lost most of what respect I had for him a few years ago.
